FLORENZ L. VEERKAMP, OF PHILADELPHIA, PENNSYLVANIA.

BOILER-FEEDER.

SPECIFICATION forming part of Letters Patent No. 407,043, dated July 16, 1889.

Serial No. 288,562. (No model.)

To aZZ w/wm it may concern:

Be it known that I, FLoRENz L. VEERKAMP, a citizen of the United States, residing in the city of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Automatic Boiler-Feeders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to apparatus for automatically feeding water to a steam-boiler or other holder of water where it is desired to keep the contained body of water therein always at a certain height; and the device which I have invented to accomplish this end consists of a cylindrical or other form of casing containing a hollow revolving water-cock, the shaft of which has its bearings in said casing, the opening in said revolving cock so arranged in connection with the exit pipe that water will only be delivered therefrom into the boiler when the water in the latter falls below the open exit end of the deliverytube.

In the accompanyingdrawings, Figure 1 is a vertical sectional view of the device with a partial sketch of a water-tank and boiler, and Fig. 2 is a lateral sectional view of the same.

A represents a horizontal boiler or holder of water, which is desired to be kept filled at all times up to a certain point.

My apparatus can be placed either upon the top of the boiler, as represented in the drawings, or upon the side thereof, but in such manner that the water in the revolving cock will descend by force of gravity.

The apparatus consists of easing B, of any suitable material, the chief functions of which are to afford bearings for the shaft E and for the pipes C and g. IVithin the casing Bis placed a hollow cylinder D, supported by the shaft E, either passing through it or secured to its heads, and upon one extremity of the shaft is placed a pulley-wheel II, which is driven by means of the belt J, connected with actuating machinery. The hollow cylinder D has an opening K, which corresponds in size with the pipes C and g. These pipes are screwed into openings in a flat netalband G, which encircles the cylinder D, and within which the latter rotates, watertight. The said pipes O and g, passing through openings in the casing, are therefore held stationary. The pipe 0 will Vary in length according to the minimum height desired of the water in the boiler. The upper pipe 9 is to be connected with a water tank F, placed above it or at any other point where water will be delivered constantly to the said pipe.

The operation of the devices is as follows: The hollow cylinder D is constantly rotated by means of its shaft, actuated by the pulley H, and thus acts as a revolving cock rotating water-tight within the encircling band G. The result is that as the opening of the hollow cylinder D is brought around in course of rotation beneath the upper pipe g water will descend into and fill the cylinder, which water will be retained within the cylinder, thus keeping always full so, long as the lower end of the pipe C is beneath the water-line in the boiler. The revolutions of the cylinder D bring the opening K also opposite the pipe C; hence, if the water in the boiler drops below the exitend of the pipe 0, the contents of the cylinder D will drop by gravitation into the boiler, and this action will be repeated upon each revolution of the cylinder D, which thus receives and deposits its water until the water in the boiler rises to a height sufficient to cover the lower end'of the pipe Having thus described my invention, I claim- A device for automatically supplying water to steam-boilers, consisting of a hollow rot-ating water-cock D, having a single inlet and outlet port K, an annular band G, adapted to fit water-tight around said cylinder, and within which the latter is rotated, said band G having inlet and outlet openings at opposite points in its periphery and corresponding with the port K of the rotating water-cock D, a pipe g, leading from the inlet-port of said annular band to a waterreservoir, and a pipe 0, leading from the outlet-port thereof to the interior of the boiler and terminating fixed my signature this 12th day of October, at the desired Water-level therein, a sup- A.

erated substantially as set forth. H. T. FENTON,
